Problems solved by technology

If the network server wants to identify the user, it can only go to the specific NAT device to find the corresponding relationship of NAT conversion. However, the implementation and application of such technology are very complicated.
In addition, in actual networks, ISPs often use multi-level NAT technology, which greatly increases the complexity of locating users. In such a scenario, it becomes more and more difficult for the server to identify users.

example 1

[0037] Example 1: Please refer to Figure 4 And 5, assuming that the IP message (user service message) carries a TCP message (equivalent to the load of the IP message), at this time the user identity can be added in the Option (option) field of the TCP header. The Option field is usually reserved for use by developers. During the three-layer forwarding and NAT processing along the message, the Option field is usually not modified, so the user identity can be successfully carried in the message and transmitted through the network to the core device.

example 2

[0038] Example 2: Please refer to Figure 4 as well as Image 6, assuming that the IP packet carries a UDP packet (the payload of the IP packet), at this time the user ID can be added at the end of the UDP packet payload, and the length of the user ID can be customized, such as 8 characters section etc. In this manner, since the UDP payload length increases, correspondingly, the length information in the IP packet header and the UDP packet header also needs to be modified. However, in a preferred manner, the present invention modifies the length information of the IP message header accordingly, while the length information in the UDP header may not be modified. The advantage of doing this is: since the devices along the way usually only process at the IP level, such as layer-3 forwarding or NAT, at most the modification of the port number will be involved at the transport level, so modifying the length value of the IP packet header can ensure that the packet is basically wi...

Abstract

The invention provides a processing device for user identity. The processing device for the user identity is applied to an access device, and comprises a first session processing unit, a first identification processing unit and a packets transmitting unit, wherein the first session processing unit is used for acquiring session features of user service messages from received user service messages and looking up a session table, and if a target is not hit, the session features are added to the session table. The first identification processing unit is used for modifying the user service messages, and adding user identify labels to the load of an internet protocol (IP) layer of the user service messages. The packets transmitting unit is used for transmitting the modified user service messages out. The invention further provides a recognition device for user identity applied to core equipment to match with the processing device for the user identity. The processing device and the recognition device for the user identity transmit the user service messages carried on a locating which usually can not be changed to a far-end of a network by skillfully using the session processing mechanism in a simple and effective mode, and enable the identification of the user identity to be more simple and reliable.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a user identity processing method and device. Background technique [0002] Network applications have penetrated into all aspects of human work and life, and the manageability of network users and the network itself is becoming increasingly important. User behavior analysis is an important technical means for the management of network users and the network itself. Through user behavior analysis, large-scale user behavior patterns and access habits can be counted, and then guide the formulation of network traffic management strategies, and at the same time enhance the security monitoring capabilities of network traffic. Existing technical solutions usually identify user traffic based on the source IP in the IP packet header. Since each user has its own independent IP address, the web server can uniquely determine a user based on the source IP to realize the user identification ...
